To all whom it may concern:

Be it known that I, ARTHUR STANLEY BA- CON,:., a citizen of the UnitedStates, and resident of Oklahoma cit in the county of Oklahoma and Stateof klahoma, have invented certain new and useful Improvements inBrick-Machines, of which the following is a specification.

My invention is an improvement in brick machines and. consists incertain novel constructions and combinations of parts hereinafterdescribed and claimed.

The object of the invention is to provide a machine of the characterspecified, especially adapted for the making of cement brick, which willreceive the plastic material and press it into shape, and having meansfor expeditiously removing the pressed brick onto a pallet for removalfrom the machine.

Referring to the drawings forming a part hereof, Figure 1 is a side viewof the improvement, Fig. 2 is a section on the line 2-2 of Fig. 1, Fig.3 is a section on the line 33 of Fig. 1, Fig. 4 is a sectional view of.a portion of the mechanism shown in Fig. 2, with the dies open, Fig. 5is a bottom plan View of a section of the lower die, Fig.

6 is a section on the line 66 of Fig. 5. Fig.

7 is a plan View of the apron, Fig. 8 is a similar view of the bottomdie, and Fig. 9 is a vertical section at right-angles toiFig. 2.

The embodiment of theinvention shown in the drawings consists of aframework composed of uprights 1 arranged in pairs, one pair at each endof the frame, and the members of each pair are connected at their topsby a cross bar 2, and each is provided with a foot 3, bolted toanI-shaped base bar 4: by bolts 5. 7

The cross bar 2 is provided at its center with a' rectangular opening -6and a top bar 7 is provided with reduced ends 8, which are received inthe openings, as shown in Fig. 2. The length of the opening 6 is greaterthan the depth of the reduced end of the bar, and a set screw 9 isthreaded through the cross bar, and engages the lower face of the end ofthe top bar. The base bars are also connected near each side of theframe by. a bottom bar 10 whose reduced ends 11 rest on the base bar,and are secured thereto by cap screws 12. The said bottom bars form partof a grid or grating, being connected at spaced intervals by cross bars13, which extend beyond the frame at one side as at 14, and form aslideway for a purpose to be presently described.

Above the extendedends 14 of the cross bars, are arranged horizontalbracket arms 15 extending from the uprights and a hop,- per 16 issupported on the arms, being secured to the frame by clips 17. Anotherpair of bracket arms 18 extend from the uprights at the opposite side ofthe frame,

and each arm isprovided on its inner face with a rest or guideway '19,and at approximately its center with a recess 20 on its upper face.

A bottom die composed of a plurality of similar sections 21 rests uponthe grid or slideway, each'section consisting of a substantiallybox-shaped structure arranged bottom upward, the upper surface 22 beingflat and the sides 23 forming a support engaging the grid. At the centerof each side wall, each section is also provided with a notch 24:, and abar 25 passes through the notches, which are in alinement.

Each notch is enlarged transversely near the edge of the side wall, asshown at 26, and a cross bar 27 is arranged beneath the bar 25, andsecured thereto, the ends of the cross bars engaging in the ends of theenlargements. A resilient bar 28 is secured to each end of thesupporting bar 25, by a cap screw 29, and the free end of each resilientbar is provided with a head 30, and

shoulders 30 and 30 are formed between the head and the bar on each sideof the said bar. The shoulder 30 is adapted to engage above theupperedge of a box, to be presently described, which encircles the dies.

The upper die 31 is in the shape of a plate, provided on its upper facenear each end with pairs of spaced lugs 32, and on its lower face withspaced parallel transverse grooves 33, and each end of the plate isprovided with an outwardly extending lug 34 near its upper face.

A. resilient bar 35 is secured to each of the lugs 34:, by a cap screw36, and the lower free end of each bar is provided with anangularportion or hook 37, for engaging ghe shoulder 30 on the bar 28 ofthe lower A box 38 rectangular in shape encircles the dies, and the-saidbox is provided at spaced intervals with transverse parallel divisionor' partition plates 39 which fit in the grooves 33, and in the spaces40' between the sections of the lower dies. The box is also provided ateach end with a flange 41 extending laterally from the end of the box,and provided with an opening 41 for the bar 35, the flange moves in thegrooves 19 of cross bars 68 on the frame.

A rod 42 is threaded into the upper face of the plate 31 at each end,and the upper end of the rod moves in a sleeve 43, on a bracket 44,secured to plates 45, extending between the uprights, by bolts 46, andthe rods act as guides for the die plate in its vertical movement.

Other rods 47 provided at each end with a head 48 are connected with thedie plate, one of the heads of each rod being received between a pair oflugs 32, and pivoted there to by a pivot pin 49, whose ends are engagedby cotter pins 50, to retain the pins in place.

The upper heads of the rods 47 are received between spaced ears 51, onthe lower ends of rods 52, whose upper ends are formed into loops 53encircling the top bar 7 A pivot pin 54 is passed through the ears andthe head, pivotally connecting the rods, and the ends of each pivot pinare extended to engage openings in the arms 55 of a yoke 56, extendinghorizontally, the parts being held in place by cotter pins 57 passingthrough the ends of the pivot pins.

The body portion of each yoke is provided with a sectional bearing 55 inwhich is journaled a crank arm 59, on a crank shaft 60, journaledtransversely of the frame. One end of the crank shaft is provided with alaterally extending lever 61 whereby to oscillate the shaft, the leverextending toward the front of the machine, as shown in Fig. 1.

A rock shaft 62 is journaled at the front of the frame, in sectionalbearings 63 on the uprights, the shaft having an arm 66, near each endbetween the uprights, and an arm 65 outside of the uprights at one endand extending toward the front of the machine. The arms 66 extenddownwardly and for: wardly to a pivotal connection with one end of links67, extending forwardly from the box inclosing the dies and pivotedthereto at their opposite ends as at 67 Each pair of rods 4752 form atoggle lever which is broken and straightened by the movement of thecrank shaft, the levers acting at one end against the upper die, and atthe other against the top bar 7.

In the operation of the machine, the plastic mixture is placed in thehopper. The guideways or grooves 19 in the arms 18 are in alinement withgrooves 19 extending across the frame in bars 68 and underneath thehopper in the bracket arms 15, so that the box may be moved from beneaththe hopper to the front of the frame. with the box beneath the hopper asshown in Fig. 9 the plastic material passes from the hopper into themolds formed by the box 38 and die .neath the upper die section 31.

sections 21. When the molds are filled, the shaft 62 is operated to movethe box 38, apron 75 and die sections 21 forwardly be- The lever 61 isnow operated to straighten the toggles 4752, thus moving the upper diedownwardly and compressing the plastic mixture in the molds. As theupper die moves downwardly, the hooks 37 of the bars 35 engage beneaththe shoulders 30 of the heads 30. The shaft 60 is then operated to breakthe toggles 4752, moving the upper die 31 upwardly and the bar 25 withthe die sections 21 supported thereby is lifted with the upper die. Thesaid die sections 21 move upwardly between the partitions 39 and liftthe blocks 7 (3 above the upper edge of the box 38 and partitions 39.lVhen the said bar 25 has been lifted to its highest position, theshoulders 30 of the bars 28 engage over the upper edge of the box, thuslocking the die sections 21 in the compartments formed between the box38 and partition 39 and with the upper surface of the die sections levelwith the upper edge of the box. The pallet 71 has meanwhile been placedon the arms 77, each of which arms is provided at its outer end with anupwardly extending lug 78 for engaging the edge of the pallet to causethe said pallet to move with the apron and molds. The shaft 62 is againoperated to move the apron, box and die sections rearwardly, and theblocks 76 engage on their rear ends the plate 69 and are held fromfurther rearward movement with the apron. As the apron continues itsrearward movement, the pallet 77 is moved beneath the blocks asindicated in Fig. 9. The shoulders 30 are now disengaged from the upperedges of the box 38 in any suitable manner, permitting the bar 25 andthe die sections 21 supported thereby to drop into the position shown inFig. 9 ready to receive another charge of plastic material. When theapron again moves forwardly, the pallet 77, blocks 76 are moved into theposition shown in dotted lines in the arms 18. The pallet and blocks maythen be removed manually, the recess 20 permitting the hands of theoperator to engage beneath the pallet. The toggle levers are meanwhilebroken, so that the upper die plate is in elevated position. WVhen thebox is in position in the frame, the shaft is oscillated, to straightenthe toggle levers, thus bringing the upper plate onto the lower with animmense pressure, thoroughly tamping the mixture into the molds formedby the upper and lower plates, the box and its partitions. As the upperplate descends, the hook 37 engages the shoulder 30, and the hook andshoulder lock with each other, and the box and plates are firmly held inthis position. It will be observed that the outer faces of the heads 30are beveled so that the hook and shoulder may be easily separated whenit is necessary. While the die plates are locked together as abovedescribed, the toggle levers are again broken, and the molds are liftedinto position level with the pallet 71 which is supported in theguideways of the bracket arms 18. The bricks 76 are now transferred tothe pallet, which may be removed from the machine by hand, the recesses20 permitting access to the bottom of the pallet from the sides. Thewear of the toggle mechanism may be compensated for by the set screws 9.It will be evident that the lower die plate may be considered as a platehaving transverse grooves to receive the partitions, and that the box isin effect a rectangular frame.

An apron 75 is mounted to slide transversely of the machine beneath thehopper, to close the bottom of the same when the lower dies are movedbeneath the upper dies v(Fig. 7) and the said apron is connected withthe upper edge of the box 38 and extends rearwardly therefrom. When thebox is moved beneath the hopper, the apron is moved rearwardly fromunder the same, and when the box is moved forwardly the apron closes thebottom of the hopper.

A plate 69 is arranged across the machine at the front of the hopper,(Fig. 1) to support the brick against rearward movement when the palletis moved under, them.

The box 88 which encircles the lower dies is locked in position aroundthe dies by the engagement of the shoulder 3O with the upper edge of thesaid box. The arms 77 extending forwardly from the apron 7 5 are adaptedto receive the pallet and support the same.
